CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefits of priority of Chineseapplication number 200920195077.3, entitled PACKAGE DEVICES FOR A DRYINGAGENT, and filed in the name of Yeung Tak Shing and Dongguan VitaPacActivated Applied Material Co. Ltd. on Sep. 21, 2009. The entire contentof the application is incorporated herein by reference.

FIELD OF THE INVENTION

The present application relates to a device for packing a drying agent.

BACKGROUND OF THE INVENTION

Long-term drying agents, such as calcium chloride, lithium chloride,potassium chloride, calcium bromide, magnesium bromide, lithium bromideand potassium bromide, gradually deliquesce from solid to become liquidby adsorbing moisture from the air, when they are used to make theenvironment in which they are placed become dry. The liquid is highlycorrosive to metallic articles, thus posing high requirements to thepackage of the drying agent.

Water-retaining agents, such as modified starch, adsorbent fiber,bentonite and attapulgite clay, are currently mixed with these dryingagent to adsorb the large amount of liquid generated during the use ofthe drying agent, in order that the liquid will not penetrate out of thepackage to corrode any articles to be dried. Nevertheless, there isstill a small amount of liquid that penetrates out of the package.Moreover, the usage of water-retaining agents will not only decrease theadsorption efficiency of the drying agent but also increase costs of thefinal product.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a packaging devicefor drying agents comprising a first compartment for containing a dryingagent and a second compartment for containing a solution. Thesecompartments are separated by a barrier plate. The barrier plate hasholes constructed thereon. A side wall of the first compartment isconstructed with windows. The packaging device is made of plasticmaterials.

Preferably, a slot mortise is formed at an end of the first compartmentthat is away from the barrier plate. An inner wall of the slot mortiseis provided with a recess.

Preferably, a tenon is formed at an end of the second compartment thatis away from the barrier plate. Outer surface of the tenon isconstructed with a protrusion. The tenon is capable of inserting intothe slot mortise through the engagement of the protrusion of the tenonwith the recess of the slot mortise.

Preferably, an anchoring plate is provided within, removably connectedto and can be fixed into, the slot mortise. A hook is provided and canbe mounted on the anchoring plate.

In an illustrative device of the present invention, the drying agent iscontained in the first compartment and the solution generated by thedrying agent is contained in the second compartment, said first andsecond compartments being separated by the central barrier plate. Thebarrier plate is constructed with holes and the side wall of the firstcompartment is constructed with windows. The window is covered with alayer of a water-proof but air-penetrable film, and a layer of water-and air-proof aluminum foil. To activate the drying agent, the aluminumfoil is removed, and the humid air in the environment penetratingthrough the air-penetrable film into the first compartment. The dryingagent placed in the first compartment adsorbs the moisture and dissolvesto become liquid which flows into the second compartment through theholes on the central barrier plate. Whenever the package isunintentionally overturned, the liquid in the second compartment willnot leak from the window due to the presence of the water-proof film.

In a preferable embodiment of the present invention, the window iscovered only with a layer of a water-proof but air-penetrable filmwithout the use of water- and air-proof aluminum foil.

In another embodiment of the present invention, a slot mortise is formedat the top of the first compartment, and a tenon is formed at the bottomof the second compartment. More than one packaging device can beconnected together through the engagement of the slot mortise with thetenon to form a chain.

In addition, a hook may be furnished at the space of the slot mortise,which can be inserted onto an anchoring plate. So, the packaging devicecan be hung.

Moreover, the package devices of the present invention are made ofplastic materials which would not be corroded by the liquid resultingfrom the deliquescence of the drying agent.

FIG. 1 is a schematic view showing the structure of the package deviceaccording to one embodiment of the invention, and

FIG. 2 is a schematic view showing the structures of the anchoring plateand the hook.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, in a first preferable embodiment of the presentinvention, a package device for a drying agent comprising a firstcompartment 10 and a second compartment 30. The first compartment 10 andthe second compartment 30 are separated from each other by a barrierplate 50. The barrier plate 50 has a plurality of hole constructedthereon. A side wall of the first compartment 10 is provided withwindows 11. The package device is made of plastic materials.

In a preferable embodiment, a slot mortise 70 is formed at an end of thefirst compartment 10 that is away from an end plate 12 opposite to thebarrier plate 50. An inner wall of the slot mortise 70 is provided withrecesses 71. A tenon 90 is formed at an end of the second compartment 30that is away from an end plate 31 opposite to the barrier plate 50.Outer surface of the tenon 90 is constructed with two protrusions 91.The tenon 90 is capable of inserting into the slot mortise 70 throughthe engagement of the protrusions 91 of the tenon 90 with the recesses71 of the slot mortise 70.

As shown in FIG. 2, in a second preferable embodiment of the presentinvention, an anchoring plate 40 is provided within, removably connectedto and can be fixed into the slot mortise 70. A hook 41 can be mountedon the anchoring plate 40. Specifically, protrusions 42 have beenconstructed at edges of the anchoring plate 40 so as to engage with therecess 71 of the slot mortise 70, so that the anchoring plate 40 isconnected to the slot mortise 70.

The anchoring plate 40 is also provided with holders 43 and 44 whichhold part 412 and part 414 of the hook 41 respectively so as to keep thehook 41 in place. When it is required to hang the package device, theparts 412 and 414 can be easily taken out from the holders 43 and 44manually. A barb 413 of the hook 41 is capable of passing through thehole 45 of the anchoring plate 40 and fixing the hook of the packagedevice, facilitating to hang the package device.

The windows 11 of the first compartment 10 are covered with a layer of awater-proof but air-penetrable film, and a layer of water- and air-proofaluminum foil. To activate the drying agent, the aluminum foil isremoved, and the humid air in the environment penetrates through theair-penetrable film into the first compartment 10. The drying agentplaced in the first compartment 10 adsorbs the moisture and dissolves tobecome liquid which flows into the second compartment 30 through theholes on the central barrier plate 50. Whenever the package isunintentionally overturned, the liquid in the second compartment 30 willnot leak out from the window 11 due to the presence of the water-prooffilm.

The slot mortise 70 is formed at the top of the first compartment 10,and the tenon 90 is formed at the bottom of the second compartment 30.Several package devices can be connected one by one through theengagement of the slot mortise 70 with the tenon 90, in order to form apackage device chain. The protrusions 91 of the tenon 90 engage with therecesses 71 of the slot mortise 70, such that several package devicescan be used in a form of package device chain. In addition, a hook 41 isfurnished at the slot mortise 70 of the first compartment 10. The hookis mounted on the anchoring plate 40 which is fixed in the slot mortise70. The packaging device can be hung through the hook 41.

The package devices of the present invention are made of plasticmaterials which would not be corroded by the liquid resulting from thedeliquescence of the drying agent.
